The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) was updated and released in 2013. Before its most recent update, the DSM used to detail a condition known as Asperger’s syndrome.
People diagnosed with Asperger’s syndrome had several symptoms in common with autistic people, but they didn’t have delays in:
- the use of language
- cognitive development
- the development of age-appropriate self-help skills
- the development of adaptive behavior
- the development of curiosity about their environment
Their symptoms were often milder and less likely to affect their daily lives than the symptoms of autistic people. They may even have been perceived as “high-functioning.”
However, high-functioning autism has never been an official clinical diagnosis, and Asperger’s syndrome was eliminated from the DSM-5 along with some other neurodevelopmental disorders.
People who have these types of difficulties with social interaction and communication or who display repetitive or restrictive behavior would now simply be diagnosed with ASD. This is regardless of how much support they may need.
